[This review was collected as part of a promotion.] This is a great price on a great product. I love the free shipping. It saves a trip to the store.

I use this oil in my Cub Cadet with a Kawasaki engine and it works great. Covers all temperatures from 100 degree summers to 0 degree winters. Stop using crappy car motor oil and switch to Rotella T6. You won't regret it.
